Mission Briefing
Our mission is to create the Smilie-O-Mat; a program that allows the user to create a smiley face that reflects his or her emotional state and posts it on Twitter. We will make three parameters adjustable: the angle of the eyebrows, the color of the face, and the position of the mouth (which is changeable, from frowning to smiling and vice-versa).
To post the image on Twitter, we are going to use a Java library named Twitter4J; we will also learn how to authorize a Processing sketch to change the status of a Twitter user using the OAuth authentication framework.
Why Is It Awesome?
You're feeling greenish-yellow today, with a little smile and neutral eyebrows. Don't know how to express that in 140 characters? No problem; adjust the face of the Smilie-O-Mat and tweet it. Life can be so easy when you have the right tools.
Besides that, accessing the Twitter data stream and then posting to it is a very rich data source for visualization projects or interactive Processing sketches...
